Pulley Demonstration Set Manufacturer,Supplier and Exporter in India

Pulley Demonstration Set (Product Code: SLE/MCE/29) is a free-standing pulley rig used to demonstrate mechanical advantage, velocity ratio and efficiency with fixed and movable pulleys in school and college mechanics laboratories. Physics teachers and engineering instructors use it to build anything from a single pulley to quadruple-sheave systems on three 81 cm steel rods, loaded with brass slotted masses. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a complete pulley system lab set in one order.

What Is the Pulley Demonstration Set Used For?

Collars with hooks slide onto the horizontal rod to carry the pulleys, and the right-angled clamps hold that rod across the vertical rods. A brass weight hanger carries the load, and slotted masses are added on the effort side until the load just rises. Comparing load with effort gives the mechanical advantage; measuring how far the effort and the load travel gives the velocity ratio, and the two together give the efficiency of the arrangement.

Because the kit contains single, triple tandem and quadruple pulleys plus a wheel and axle, one set covers the whole progression from a simple fixed pulley to block-and-tackle systems and other simple machines, making it practical mechanics lab equipment in India for beginner and advanced classes alike. The base also carries a capstan and an eye hook for cord arrangements. Before loading, tighten the vertical rods with the tommy bar, keep the cord running squarely in each groove and add masses gently so that swinging does not upset the readings.

What to Specify When Ordering

• Number of complete sets needed for your student groups
• Extra cord rolls, if classes re-string the pulleys often (4 rolls come with each set)
• Additional slotted brass masses or weight hangers beyond the standard assortment
• Spare single, triple tandem or quadruple pulleys for replacement
• Delivery location in India or abroad

OEM Manufacturer

ScienceLab is the OEM behind this Pulley Demonstration Set. Jain Scientific Equipments Private Limited, which trades as ScienceLab, makes it at its own licensed factory at Saha, Ambala, Haryana, India, instead of buying it in from a trader. Schools, colleges, laboratory dealers and importers therefore order factory-direct from the team that assembles the rods, pulleys and base.

For replacement pulleys, cord or masses on sets already in service, ask us and the manufacturer will advise on what can be supplied. More about the company is on the ScienceLab company profile.

Related Theory of Machines Equipment

These items are used alongside the pulley set when a class works through simple machines, forces and power transmission:

• Force Meter/Spring Balance — reads the effort directly instead of balancing it with slotted masses.
• Slotted Mass Hanger, 1kg — carries heavier loads on multi-pulley arrangements.
• Balance Demonstration Fulcrum/Lever — lets students compare lever advantage with pulley systems.
• Gear Train Model — the next step: velocity ratio in gear drives.
• Friction Slide Apparatus — explains the friction losses that keep real pulley efficiency below the ideal.

The Pulley Demonstration Set comes with slotted brass masses of 2 x 10 g, 2 x 20 g, 2 x 50 g, 4 x 100 g, 4 x 200 g and 1 x 500 g, plus brass weight hangers of 5 x 50 g, 1 x 20 g and 1 x 10 g for building up loads and efforts.

Which topics can students study with the Pulley Demonstration Set?
With the Pulley Demonstration Set, students study fixed and movable pulleys, block-and-tackle systems, mechanical advantage, velocity ratio, efficiency and the wheel and axle. The mix of single, triple tandem and quadruple pulleys lets one kit serve both beginner and advanced mechanics classes.

Who manufactures the Pulley Demonstration Set?
The Pulley Demonstration Set is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Orders, quotations and spare-part requests are handled directly by the manufacturer rather than through a reseller.

Can I get replacement pulleys or cord for the Pulley Demonstration Set later?
You can ask for replacement pulleys, cord rolls or slotted masses for an existing Pulley Demonstration Set through our contact page. Tell us which parts and how many you need, and the manufacturer will confirm what can be supplied.

What should a quotation request for the Pulley Demonstration Set include?
For a Pulley Demonstration Set quotation, state the number of sets, any extra masses, cord or spare pulleys, and the delivery location in India or abroad. Institutions equipping several laboratories can ask for one consolidated quotation for bulk supply.
